The D6 Star Wars Role Playing game was created by West End Games. The company acquired the right to produce a Star Wars RPG in 1987. WEG established much of the Star Wars lore that later became the expanded universe (EU) and produced guidebooks and sourcebooks for many of the initial EU novels. In 1998, despite a successful product, they went into bankruptcy as a result of poor financial management. The company lost its rights to Star Wars.
Still, the D6 system was very popular. For one, it only used six sided dice (it's namesake), dice common to most all board games ever created, and not as obscure as some of the dice used in other Role Playing games. Second, the company wasn't about putting out flashy D&D style guides that stressed visual presentation over content. Instead, they covered each topic they chose as in depth as possible. Each guide and sourcebook they produced was full of a wealth of knowledge on the covered subject, and they put out many books over their run. Third, they supported their player base, constantly updating their game, adding new content, places, characters and items, through the various guides, books, magazines, and newsletters they published.
Today, many Star Wars gamers still love the D6 system and use it. The books are eagerly bought on Ebay and home brewed material is still very prevalent online. Although there is a newer Star Wars RPG produced by Wizards of the Coast, it failed to capture the player base that the original did. Their system was based around the 20 sided die, often being referred to as D20 Roleplaying. This line is currently not being produced anymore as well.
